The problem is Asus tweak, Afterburner, Trixx, etc,etc...all conflict with AMD/Wattman controls and settings. Delete it. Before you do, use it to set everything back to application default settings. Set Wattman back to 'Factory Defaults'.

In Global settings/Global Wattman....set Power Limit to +50 (or all the way to the right). Leave everything else at default 'automatic'. Click 'Apply' at the top of the page.

I have an Asus GPU, so I had the Asus GPU Tweak software installed. After installing the update and watching what happens on reboot, I discovered that the crash happened as soon as GPU tweak started, and that it was accompanied by a message about wattman being reset. I knew I had a slight "over"clock on my GPU, but I didn't even think about that being the cause of it. I booted into safe mode, opened up services and disabled the ASGT service (Asus GPU Tweak). When I restarted.... everything worked properly! I then uninstalled the software. Looks like I'll be doing all my adjustments through the built in AMD software from now on.......

Hello, for your problem try downgrade, to the 17.5.2 driver version, the versions 17.6.1, 17.6.2 and 17.7.1 has a issue with framebuffer its stuck at 100%, you dont see diferences in fps, but you notice stutter, from time to time... I play this game at 4K 60 clean fps, with RX580, FX8350, 16GB DDR3 1866 in a HDD 5400rpm.
